Scala Iterator addString()用法及代碼示例

此方法與addString()方法相同，但在這裏我們甚至可以在Iterator的所有元素之間包括分隔符。

函數定義： def addString(b:StringBuilder, sep:String):StringBuilder
Where, sep is the separator.

返回類型：It returns the elements of an iterator in the String Builder along with the separator stated.

範例1：

// Scala program of addString() 
// method along with separator 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating an Iterator  
        val iter = Iterator(11, 12, 13, 14) 
          
        // Applying addString method 
        // with a separator 
        val result = iter.addString(new StringBuilder(), "#") 
          
        // Displays output 
        println(result) 
      
    } 
}

輸出：

11#12#13#14

範例2：

// Scala program of addString() 
// method along with separator 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating an Iterator  
        val iter = Iterator(5, 6, 9) 
          
        // Applying addString method 
        // with a separator 
        val result = iter.addString(new StringBuilder(), "*") 
          
        // Displays output 
        println(result) 
      
    } 
}

輸出：

5*6*9
